DBRS Confirms AAA (sf) Rating on Thrones 2013-1 Plc

DBRS Ratings Limited (DBRS) has today confirmed the AAA (sf) rating on the Class A Notes issued by Thrones 2013-1 Plc (the Issuer).

The rating assigned to the Class A Notes addresses the timely payment of interest and ultimate payment of principal.

The confirmation of the rating on the Class A Notes is based on the following analytical considerations as described more fully below:

-- Portfolio performance, in terms of delinquencies and defaults, as of March 2016.
-- Probability of default (PD), loss given default (LGD) and expected loss assumptions for the remaining collateral pool.
-- Current available credit enhancement to the Class A Notes to cover the expected losses at its current rating level.

The Issuer is a securitisation of first-ranking U.K. non-conforming residential mortgages originated by Heritable Bank Plc. The mortgage portfolio is serviced by Mars Capital Finance Limited, with Homeloan Management Limited acting as the backup servicer.

As of March 2016, two- to three-month arrears were at 1.95%, and the 90+ delinquency ratio was at 2.38%. Current realised losses are low at 0.63%.

As of April 2016, credit enhancement to the Class A Notes was 43.43%, up from 30.50% at the DBRS initial rating. Credit enhancement to the Class A Notes consists of overcollateralisation and a reserve fund.

As of April 2016, the reserve fund was at the target level of GBP 4.87 million and is available to cover senior fees, Class A interest and Class A principal.

The DBRS private rating of Citibank N.A., London Branch complies with the Minimum Institution Rating, given the rating assigned to the Class A Notes, as described in DBRS’s “Legal Criteria for European Structured Finance Transactions” methodology.

To assess the impact of changing the transaction parameters on the rating, DBRS considered the following stress scenarios as compared with the parameters used to determine the rating (the base case):
-- DBRS expected a lifetime base case PD and LGD for the pool based on a review of the current assets. Adverse changes to asset performance may cause stresses to base case assumptions and therefore have a negative effect on credit ratings.
-- The base case PD and LGD of the current pool of mortgages for the Issuer are 13.41% and 20.14%, respectively. At the AAA (sf) rating level, the corresponding PD is 42.96% and the LGD is 44.75%.
-- The Class A Notes Risk Sensitivity overview below illustrates the ratings expected if the PD and LGD increase by a certain percentage over the base case assumption. For example, if the LGD increases by 50%, the rating of the Class A Notes would be expected to remain at AAA (sf), assuming no change in the PD. If the PD increases by 50%, the rating for the Class A Notes would be expected to remain at AAA (sf), assuming no change in the LGD. Furthermore, if both the PD and LGD increase by 50%, the rating of the Class A Notes would be expected to fall to AA (high) (sf).

Class A Notes Risk Sensitivity:
-- 25% increase in LGD, expected rating of AAA (sf).
-- 50% increase in LGD, expected rating of AAA (sf).
-- 25% increase in PD, expected rating of AAA (sf).
-- 50% increase in PD, expected rating of AAA (sf).
-- 25% increase in PD and 25% increase in LGD, expected rating of AAA (sf).
-- 25% increase in PD and 50% increase in LGD, expected rating of AAA (sf).
-- 50% increase in PD and 25% increase in LGD, expected rating of AAA (sf).
-- 50% increase in PD and 50% increase in LGD, expected rating of AA (high) (sf).
